Effective Use of Keishibukuryogan in Subcutaneous Hematoma after Implantable Cardiac Device Surgery in Two Cases.

Keishibukuryogan is a Kampo medicine that induces vasodilation and improves the blood flow velocity in subcutaneous blood vessels. We herein report two cases in which keishibukuryogan completely diminished subcutaneous hematoma after cardiac resynchronization therapy pacemaker implantation and defibrillator battery replacement within a month. Keishibukuryogan can be a good option for treating or preventing subcutaneous hematoma after surgical procedures for devices.

Cryoballoon Ablation Induced Hyperkalemia due to Possible Cold Agglutinin Disease.

Cryoballoon ablation is a well-established therapeutic tool for paroxysmal atrial fibrillation (PAF). We herein report a rare case of a 69-year-old man with PAF undergoing hemodialysis due to chronic kidney disease who developed hyperkalemia caused by possible cold agglutinin disease during cryoballoon ablation therapy. During the procedure, his electrocardiogram showed wide QRS when we finished cryoablation therapy.

New tailored approach using a revised assessment of fragmented potentials for persistent atrial fibrillation: Early area defragmentation by modified CFAE module.

Introduction: Pulmonary vein isolation (PVI) is widely performed for atrial fibrillation (AFib). However, it is insufficient to maintain sinus rhythm (SR) in persistent and long persistent atrial fibrillation (Per-AFib). Ablation of complex fractionated atrial electrograms (CFAEs) is currently classified as class IIb, However, the concept of length of potential was different between the current CFAE module of CARTO system and the definition of CFAE potential.

Ezetimibe combined with standard diet and exercise therapy improves insulin resistance and atherosclerotic markers in patients with metabolic syndrome.

Aims/introduction: Ezetimibe lowers serum lipid levels by inhibiting intestinal absorption of dietary and biliary cholesterol. However, the effect of ezetimibe on insulin resistance remains unclear. The aim of the present study was to examine this issue in patients with metabolic syndrome in local-dwelling Japanese, who were not being treated with lipid-lowering drugs.

Association of serum eicosapentaenoic acid to arachidonic acid ratio with microalbuminuria in a population of community-dwelling Japanese.

Background: Epidemiological evidence suggests that the increased intake of omega-3 polyunsaturated fatty acids can prevent atherosclerosis-related cardiovascular diseases. Recently, serum eicosapentaenoic acid to arachidonic acid (EPA/AA) ratio has been reported to be a predictive marker of cardiovascular events. Accordingly, we examined the relationship between serum EPA/AA ratio and microalbuminuria.

Plasma Renin Activity and Resting Heart Rate in a Population of Community-Dwelling Japanese: The Tanushimaru Study.

Background: Heart rate is a strong predictor of mortality and development of obesity and diabetes. The renin-angiotensin-aldosterone system plays an important role in blood pressure control and volume homeostasis. Although many studies have indicated the association between aldosterone and hypertension or insulin resistance, epidemiological evidence of the association of heart rate with plasma renin activity (PRA) remains scant.

High plasma fetuin-A levels are associated with metabolic syndrome among males but not females in a Japanese general population.

Aims: Fetuin-A, a protein exclusively secreted from the liver, is associated with insulin resistance and/or metabolic syndrome (MetS). However, few studies have examined this association in Japan. We investigated this issue in a Japanese general population.

Serum vaspin levels are positively associated with carotid atherosclerosis in a general population.

Objectives: Vaspin is a novel adipocytokine with potential insulin-sensitizing properties. Insulin resistance (IR) plays a role in the development and progression of atherosclerosis. However, the relationship between serum vaspin levels and atherosclerosis remains unknown.

Serum uric acid is associated with the left ventricular mass index in males of a general population.

The association of serum uric acid (UA) with left ventricular hypertrophy (LVH) remains controversial. We investigated this issue in a general population. Participants consisted of 1,943 subjects (774 males and 1,169 females) aged over 40 years, living in Tanushimaru (a Japanese cohort of the Seven Countries Study).

Circulating Inflammatory and Hemostatic Biomarkers are Associated with All-Cause Death and Cancer Death in a Population of Community-Dwelling Japanese: the Tanushimaru Study.

Background: In patients with cardiovascular diseases, inflammatory and hemostatic biomarkers are significant indicators of prognosis. We investigated whether circulating inflammatory and hemostatic biomarkers were predictive markers for all-cause death and cancer death in a population of community-dwelling Japanese.

Methods: We studied 1,920 healthy Japanese adults who underwent health examinations in 1999.

High level of plasma remnant-like particle cholesterol may predispose to development of hypertension in normotensive subjects.

Background: Remnant-like lipoprotein particle cholesterol (RLP-C) is a highly atherogenic factor. RLP-C induces endothelial dysfunction and is associated with hyperinsulinemia. This study was designed to determine whether high plasma RLP-C levels predispose to the development of hypertension in subjects with normal blood pressure (BP).

New computer model for prediction of individual 10-year mortality on the basis of conventional atherosclerotic risk factors.

Background: Large cohort studies have revealed that subjects with atherosclerotic risk factors have high mortality. However, there has been no method to predict individual mortality based on these risk factors. Accordingly, we developed a computer model predicting the 10-year mortality of an individual with atherosclerotic risk factors.
